Electromagnetic penetration and coupling to wires through apertures of arbitrary shape

Electromagnetic (EM) coupling through apertures of arbitrary shape in a perfectly conducting infinite screen of negligible thickness, is considered. In particular, general configurations that include the presence of wires are analyzed. These latter may be asymmetrically located on both sides of the aperture, with some element passing through the aperture. The problem is formulated in terms of an integral equation involving (as unknowns) the equivalent magnetic current at the aperture and the electric current distribution on the wires, which is, therefore, solved by the method of moments (MoM). A set of measurements has been conducted to verify the accuracy of the technique.
